Causes

Damaged or corroded wiring or connector to the rear vertical acceleration sensor
Loose or broken sensor mounting or bracket (mechanical shock/noise)
Water ingress or contamination of the sensor connector
Failed rear vertical acceleration sensor (internal electronics)
Faulty chassis/stability control module or poor ground at control module
Incorrect or missing sensor calibration/relearn after repair

Symptoms

ABS/ESP/DSC/stability light illuminated
Suspension/air ride or ride height warning messages (if fitted)
Fault codes stored for stability or sensor circuits
Possible poor vehicle stability control behavior (reduced performance)
Noisy or abnormal behavior from the rear suspension (if mounting loose)

What to check

Read stored and pending codes and capture freeze frame / live data with a diagnostic scanner
Visually inspect sensor and connector for corrosion, damage, water ingress and secure mounting
Check wiring harness route for chafing, pinched or broken wires between sensor and control module
Perform wiggle test on harness while monitoring live sensor data for intermittent change
Measure sensor supply and signal voltages at the connector with ignition ON (compare to spec)
Check for proper ground continuity between sensor ground and vehicle chassis/ECU ground

Signal parameters

Typical 3‑wire MEMS accelerometer: reference supply (5V or vehicle reference), signal (analog voltage proportional to vertical acceleration), ground
At 0 g the signal often sits near mid‑supply (e.g., ~Vcc/2) — consult model service data for exact voltage
Output sensitivity typically expressed in mV/g; expected small voltage change around idle/static conditions
Signal should be stable with low noise when vehicle is stationary and vary smoothly with vertical motion
Check for short to power (signal ≈ Vref) or short to ground (signal ≈ 0V) or open circuit (no signal/read error)

Diagnostic algorithm

Use a capable scan tool to read C110B and related codes, record freeze frame and observe live rear vertical accel data.
Visually inspect sensor, mounting, and connector for damage, water or loose bolts. Tighten or secure mounting as required.
With ignition ON (engine off), backprobe sensor connector: verify reference supply, ground continuity and signal voltage. Compare with manufacturer specification.
Wiggle harness and connector while monitoring live sensor output to check for intermittent faults.
If signal is shorted or open, trace wiring with a DMM for continuity and shorts to battery positive and ground; repair wiring or connector as needed.
If supply and ground are correct but signal is implausible or noisy, replace sensor and re-check function.
After repair or sensor replacement, clear codes and perform required sensor/module calibrations or relearns per service manual; road test and monitor for code return.
If fault persists after sensor and wiring verification, inspect chassis/stability control module power/ground and consider module testing or replacement following manufacturer diagnostics.

Likely causes

Open or short in sensor harness (most common)
Corroded/poor connector contact at sensor
Sensor failed due to impact or water damage
Sensor mounting loosened or damaged altering output
Intermittent connection due to chafing or broken wire

Fault status

⚠️ Status

Rear vertical acceleration sensor signal fault detected — chassis control module has recorded an out‑of‑range or missing signal for the rear Z‑axis accelerometer.

🟡 Repair difficulty: Medium

⏱️ Diagnostic time: 0.5-2.0 hours
